So Apple is offering a podcast hosting service, but it uses some proprietary thing instead of RSS and DRM's the audio so other podcast clients can't play them, and the podcast owner can't easily switch to a different podcast host (including one that this post's author runs). It doesn't tell the podcast owner that. I have never used a podcast, so is this all correct? If so, I agree this is a deliberately snaky move on Apple's part.
